WINDOW REGULATOR Application led 'February 23.1926. Serial No. 90,108.

The invention relates to Window regulators and has for its main object the provision of a unitary structure in which the window regulator is built into the panel forming a wall of the chamber into which the closure is adapted to be moved.` Another object is to form the panel in a manner to guide the control arm of the window regulator and to also receive the irreversible drive mechanism for the control arm and the closure counterbalancing spring. Further objects of the invention reside in the novel features of construction and combinations and arrangements of A It has been the customary practice heretoj fore to form the window regulator as an independentunit of the frame in which the window is slidably mounted and also to independently form the inner panel of the frame whichV forms a wall ofthe frame chamber.

With lmy invention the panel and window i the window regulator and Ythe latter might be said tobe built into the panel. As specifically shown, my invention is applied to an all-steel vehiclevdoor 1 having an opening 2 in its upper portion Yanda chamber 3 in its lower portion, the inner wall of this chamber beingv f formedby the sheet steel panel 4. 5 is the 4fwindowvor closure for the opening 2 slidably mounted in suitable guideways in the door frame from a closed` position into the A l chamber.

Vmounted upon the panel 4 and in the present Y instance is rigidly secured to the gear segment 9. This gear segment is fixed upon the v i shaft 10, which is journaled in the panel and extends transversely thereof. 11 is a pinion meshing with the gear segment and driven by suitable irreversible drive mechanism 12.67A

from the handle shaft 13, the inner end 'of which has a suitable handle secured thereto. 14 1s a cupped casing for enclosing the irreversible drive mechanism and also formingV agg;

bearing in which the handle shaft is journaled.

. For counterbalancing the weight ofthe closure 5, I have 'provided the convolute spring 15 which has its` inner end rigidlyse-o cured to the shaft 10 and its outer end providedwith a hook 16 for engaging an anchor 17 upon the panel.

To properly posltion and .also guide-the control or lifter arm 6 and also to securethe minimum thickness of doorl the `panel 4 is outwardly depressed to form the laterally yoffset wall 18 and the depression 19 at the inner side of this laterally osetwall. The

pivot 10 is journaledy in this laterally ofsetg'w wall and the gear-.segment 9 'and control or lifter arm 6 are located adjacent to the outer side of this wall. Furthermore, this laterally offset wall. is provided with the struck out tongue 20 which is engageable with the outer ,f1.5 side of the gear segment to assist in guiding the same. This tongue 20 additionally forms f a bearing in which is j ournaled the shaft 21 upon which the pinion 11 is formed. vThe depression 19 formedin the panel receives the "Q0 irreversible drive mechanism 12 and its enclosing casing 14 and also receives the closure counterbalancing spring 15 as kwell as the anchor 17 which isspecifically formed by means of the tongue 22 struck out from the c5 laterallyofset wall 19. j

What I claim as my invention is l. The combination of a frame having an'k opening and a chamber adjacent said opening, a metallic panel forming one wall ofsaid zoo chamber and having a depressed portion with v a laterallyv offset wall, a. movable closure for .A the opening, an arm connected to said closure and located adjacent one side of lsaid wall, and a drive mechanism connected to said arm 195 and located in said depressed portion at the opposite side of said wall. Y

'lao

chamber and having a depressed portion With a laterally oset Wall, a tongue struck out from said laterally offset Wall and extending into the depression, control mechanism for said closure including an arm operatively connected to said closure, irreversible drive mechanism for said arm and a counterbalancing spring for said closure operatively connected `to said arm, said arm being adjacent to one side of said laterally offset Wall and said ir' reversible drive mechanism and counterbalancing spring being adjacent to the other side and located in the depression, said counterbalancing spring being anchored to said tongue.

3. The combination cfa :traine having an openingand a chamber adjacent saidopening,a metallic panelforming one Wall of said 4 `chamber and having a depressed portion with y a laterally oifset Wall, said laterally o'set wall being provided with a pair of tongues struck out therefrom, control mechanism for `Said closure including a plvotal ai'in'operativelyconnecte'd to said closure, a gear segment secure-d to said arm and guided by `one -of said tongues, a pinion meshing with said gear segment, and a convolute counterbalancing spring for said closure operatively connected to said arm, said arm and gear segment being adjacent to one side of said laterally offset wall and said counterbalancing spring being adjacent to the opposite side and located -in the depression and having one end an- `chored to the other of said tongues.
